School administrative spaces including reception;

Library with reading nooks, makers space and research pods;

Staff rooms and offices;

Special programs rooms;

Amenities;

Canteen;

Interview rooms; and

Presentation spaces.

Construction of four 2-storey classroom buildings (Block B) containing 40 homebases comprising:

Collaborative learning spaces;

The purpose of this site infrastructure report is to provide a review of the existing Electrical, Mechanical, Hydraulic and

Fire protection services (MEP Services) site infrastructure services at Alex Ave. Public School as part of the schematic

design.

This site a green field site and our review is based on the available information from Dial Before You Dig (DBYD) and

relevant Arch. drawings and master planning.

1.2 CONSULTANT SCOPE

WSP/PB will provide a high-level summary of the existing site MEP services and proposed services to the site.

1.3 ASSUMPTIONS AND CONSTRAINTS

This report will only review the school site infrastructure and the associated plant.

The review has been carried out using available DBYD information and relevant available drawings.

As part of this review, as a minimum, Educational Facilities Standards and Guidelines (EFSG) have been considered.

The followings constraints have been identified following the site visit and initial review;

- Further detail review of the Authority infrastructure is required to identify the exact locations and capacity of the

Authority mains.

- Augmentation or upgrade of the Authority infrastructure – Subject to further coordination and confirmation with

relevant Authorities and application.
